How to choose your first telescope
Aperture, mounts, and the one mistake beginners make — a buyer's guide that won't steer you wrong.
The right first telescope is the one you'll actually carry outside and enjoy using. The wrong one — usually a flimsy, over-magnified department-store special — ends up in a closet.
Here's what actually matters, in order, so you can buy once and observe for years.
Aperture beats magnification
Aperture — the diameter of the main lens or mirror — is the single most important spec. It determines how much light the telescope gathers and how much detail you can see. Ignore the giant '500x!' magnification claims on the box; those are marketing, and high power on a small scope just shows a big, dim blur.
For a first scope, look for at least 100–150mm (4–6 inches) of aperture. More aperture shows fainter galaxies and finer planetary detail — but also costs more and weighs more.
The three main types
Each design trades cost, portability, and what it's best at. There's no single 'best' — only best for you.
- Refractors — lens-based, low-maintenance, great on the Moon and planets; pricey per inch of aperture
- Reflectors (Newtonians) — mirror-based, the most aperture for your money, superb for deep-sky; bulkier
- Compound (SCT / Maksutov) — compact tubes with long focal lengths, versatile, often go-to capable; cost more
Don't skimp on the mount
A great telescope on a wobbly mount is useless — every touch sends the image shaking. A stable mount is half the experience.
A simple Dobsonian (a Newtonian reflector on a smooth rocker base) gives beginners the most aperture and the least frustration for the money. Motorized 'go-to' mounts find objects for you but add cost and setup; decide whether you'd rather learn the sky or let the scope do it.
Realistic first-night expectations
The Moon will be jaw-dropping. Saturn's rings and Jupiter's moons are easy and unforgettable. Bright star clusters and a few nebulae will show from dark skies. But faint galaxies look like grey smudges, not the colourful Hubble photos — that's normal, and dark skies help enormously.
